Isingeniso sokusetjenziswa, izinto eziqakathekileko kanye nobujamo be-wafer check valve

Hlola ivalvu kutjho i-valve evula begodu ivale ngokuzenzakalelayo i-valve flap ngokuthembela ekugelezeni kwe-medium ngokwayo ukukhandela ukugeleza emuva kwe-medium, eyaziwa nangokuthiivalvu yokuhlola, ivalvu yendlela eyodwa, ivalvu yokugeleza emuva kanye nevalvu yokugandeleleka emuva. Iivalvu yokuhlolayivalvu ezenzakalelayo umsebenzi wayo omkhulu ukukhandela ukugeleza emuva kwe-medium, ukujikeleza emuva kwepompo ne-motor etjhayelako, nokukhutjhwa kwe-medium ngaphakathi kwekhonteyina. Amavalvu wokuhlola angasetjenziswa godu emigqeni enikela ngeenhlelo ezisizako lapho umfutho ungakhuphuka ngaphezu komfutho wesistimu.

1.Tukusetjenziswa kwevalvu yokuhlola i-wafer:

Iivalvu yokuhlola ifakwe erherhweni lamapayipi, begodu umsebenzi wayo omkhulu kukhandela ukubuyela emuva kwe-medium. Iivalvu yokuhlolayivalvu ezenzakalelako evulwa begodu ivalwe ngokuya ngomfutho ophakathi.Ivalvu yokuhlola i-wafer ilungele ukugandeleleka kwe-PN1.0MPa~42.0MPa, iKlasi150~25000; ububanzi obubizwako DN15~1200mm, NPS1/2~48; Ukubuyela emuva okuphakathi. Ngokukhetha izinto ezihlukahlukeneko, ingasetjenziswa eendaweni ezihlukahlukeneko ezifana namanzi, umtjhiso, amafutha, i-nitric acid, i-acetic acid, i-oksidizi eqinileko kanye ne-uric acid.

2.Tinto ekulu yeivalvu yokuhlola i-wafer:

Kune-carbon steel, i-low temperature steel, i-dual phase steel (F51/F55), i-titanium alloy, i-aluminium bronze, i-INCONEL, i-SS304, i-SS304L, i-SS316, i-SS316L, i-chrome molybdenum steel, i-Monel (400/500), i-Hastelloy nezinye izinto.

3. Iimpawu zesakhiwo seivalvu yokuhlola i-wafer:

A. Ubude besakhiwo bufitjhani, begodu ubude besakhiwo buyi-1/4 ~ 1/8 ye-valve yokuhlola ye-flange yendabuko

B. Ubukhulu obuncani nobudisi obulula, ubudisi bayo buyi-1/4 ~ 1/20 ye-valve yokuhlola ye-flange yendabuko

C. Idiski yevalvu ivala msinyana begodu umfutho wesando samanzi mncani

D. Amapayipi avundlileko nofana athe ngqo angasetjenziswa, kulula ukuwafaka

E. Itjhaneli yokugeleza ibutjhelelezi begodu ukujamelana kwe-fluid kuncani

F. Isenzo esibucayi nokusebenza okuhle kokuvala

G. Ukukhamba kwe-valve disc kufitjhani begodu amandla wokuvala womthelela mancani

H. Isakhiwo soke silula begodu sincani, begodu ijamo lihle

I. Isikhathi eside sokusebenza nokusebenza okuthembekileko

4.TAmaphutha avamileko we-valve yokuhlola:

A. Idiski yevalvu iphukile

Umfutho we-medium ngaphambi nangemva kwevalvu yokuhlola usebujameni bokutjhidela ekulinganiseni kanye "nesaha" elifanako. Idiskhi yevalvu ivamise ukubethwa ngesihlalo sevalvu, begodu idiski yevalvu eyenziwe ngezinto eziphukileko (ezifana nensimbi, ithusi, njll.) iyaphuka. Indlela yokuvikela kukusebenzisa i-valve yokuhlola ene-disc njengento ethambileko.

B. Ukubuyela emuva okuphakathi

Indawo yokuvala ilimele; ukungcola kuvalelekile. Ngokulungisa indawo yokuvala nokuhlanza ukungcola, ukugeleza emuva kungavinjelwa.
